    A Special Note about Email accounts!
    DO NOT SIGN UP USING hotmail, outlook, gmx, sbcglobal, att, bellsouth or email.com. They delete our forum signup emails.

    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

I can't find the problem for the life of me... Gs400 1977

Two years ago, I finally got the bike running flawlessly, or so I thought. The carbs were perfect then suddenly, gas was pouring out of the overflow. One of the metal floats had a pin hole in it and it let too much gas in. I purchased new floats only not metal. Installed and I had amazing power throughout all bands. Then, again the gas started pouring out and it was due to incorrect float height. Now I've adjusted the heights to spec and there is simply no power. Bike runs and idles well. But the oomph has completely dissipated. It struggles going up hills and sputters as if it's about to go fast but then bogs down. Any thoughts? Change the float height more? Clean the carbs again?
 
My floats are round. I have the bs34 carbs. And I mean bs34 not bs34ss... I just raised the float height 1mm from 26.3 to 27.3. I took her out for a ride and noticed an improvement. I believe I'm going to try raising it another mm to lean it out some more and see if there's any more improvement. So far signs are leaning towards a too rich mixture.
 
Good to see that you understand that raising the number related to the float height actually leans out the overall mixture. :clap: :clap:

Yes, 26.3mm is the standard figure, but that is also with standard floats. More important is to get the FUEL LEVEL correct, which it needs to be, regardless of what float is being used. Find a way to measure your actual fuel level (it is illustrated in all the manuals), make sure it is 6.5mm +/- 0.5mm.
